a device of the character mentioned which will be. of such construction as to be particularly applicable for use'l in the event of the couplers of a railway car pulling out o1' being otherwise disabled.

A furthenobject is to provide a coupling device as mentioned which may be expefan enlarged detailof thel'clamping means` ditiously and readily applied, and which,

when applied, will be adapted to efliciently serve inthe capacity of a car coupler, another object being to'provide a coupler which will be' strong and durable, compara-tively simple of construction, hence of low cost to manufacture.

f OtherobjeCts will appear hereinafter.

l With these objects 1n view, our invention consistsffina coupling device characterized as yabove; mentioned and in certain details ofv construction and arrangement of. parts all aswill be vhereinafter fully described' and particularly ointed out in the claims.

Our inventlon will be'morereadily understood by reference to the' accompanying drawings forming tion, and in. which,

In use our device is preferably applied to the front end-beam of the rear car and the rear end-beam of the front car to be coupled, althoiiglithe same ymay be applied to any other suitable support provided at the adjacent ends of the cars.

While we have shown what we deem to be the preferable form of our device, We donot wish,v to be limited thereto, asthere might be manychanges made in the details lof construction and arrangement of parts without departing from the spirit of our invention. i And while we have designed our dvicc i with special reference to railway ears, we may use the same 1n any other` connection to which it is applicable.

j Having described our invention what We Iatent is:V i

1. In a coupling devlce, the combination of similar clamping means comprising a bar;

provided with a notch adapted to receive the flange of a car end'beam; a jaw adjustable on said bar and provided with a notch adapted ble connection between said clamping means, substantially as described. A

2. lIn a coupling device, the combination of similar clamping means comprising abar; a jaw formed at one end of said bar and provided with a notch adapted to'receve Athevflange of a car end beam, and a tooth adapted to enter the side of a woodenl beam; a jaw adjustable' on said bar and provided with a notch adapted to receive a car en d beam, and a tooth adapted to enter the side of wooden beam and a flexible lconnection between-said clamping means, 'substantially as described.

2. In a coupling device, the combination ofsiifiilarl clamping means comprising the bar 2 vhaving teeth 6 o n' its upper face; jaw

member 3 slidably mounted on said bar fand provided with the notch 21; gear 25 mounted in member and provided with the hanil dle 2G and a flattened side 27.; and a flexible i connection'-between said clamping means, i substantially as described.

4. In a coupling device, the combination of similar clamping meanscomprising the bar 2 having teeth 6 in yits upper face and slot 8 in itsend; jaw 14 on bar 2 provided i with the notch 16 and tooth ,17 ,member 3 slidably 'mounted on said bar and provided with the notch 21 and tooth 18 gear 25 mounted in member 3 and provided with the handle 26 and the flattened side 27 cable 10 taking through slot 8; and clamping means for securing the end of the cable, substantially as described.
